The present embodiment relates to a kind of data transmission method, by the RCS standard, is defined.Wherein, the RCS normalized definition comprise the IM network architecture of IM-AS, IMS and UE, and IM-AS is positioned at the operation layer of IMS, refers to the network architecture diagram of the IM shown in Fig. 1.

Please refer to Fig. 2, it shows the method flow diagram of the data transmission method that one embodiment of the invention provides.This data transmission method comprises:

Step 201, a UE detects whether with controlling node, set up the first public MSRP passage, and this first public MSRP passage is for transmitting a UE and controlling all information between node; If testing result, for controlling node, having set up the first public MSRP passage, performs step 202;

The first public MSRP passage is for transmitting a UE and controlling all information between node.Such as, the information that the foundation that a UE sends to the control node or the information disconnected, a UE send to other-end, the information that other UE send to a UE etc.Wherein, controlling node can be IM-AS.

Because a UE need to communicate by letter with other UE by controlling node, therefore, a UE, before transmission information, needs to detect and whether with the control node, has set up the first public MSRP passage.

Step 202, a UE sends the communication information by the first public MSRP passage to controlling node, and this communication information carries the sign of data, a UE and the sign of the 2nd UE, and the 2nd UE is for receiving the UE of data;

Because a UE has set up the first public MSRP passage with controlling node, therefore, a UE can send the communication information to controlling node by this first public MSRP passage.Wherein, the communication information can comprise the sign of data, a UE and the sign of the 2nd UE.Data are contents that a UE need to transmit, and can be word message, image information and file etc.The sign of the one UE is used for the transmit leg of identification data.The sign of the 2nd UE is for the recipient of identification data.

Step 203, control node and receive by the first public MSRP passage of setting up in advance the communication information that a UE sends;

Step 204, control node and determine the second public MSRP passage according to the sign of the 2nd UE, and this second public MSRP passage is for transmitting the 2nd UE and controlling all information between node;

After the control node receives the communication information, read the sign of the 2nd UE in this communication information, determine the 2nd indicated UE of sign that the communication information need to be transmitted to the 2nd UE, control node and can determine the second public MSRP passage of setting up with the 2nd UE according to the sign of the 2nd UE.

Wherein, the second public MSRP passage is for transmitting the 2nd UE and controlling all information between node.Such as, the information that the foundation that the 2nd UE sends to the control node or the information disconnected, the 2nd UE send to other-end, the information that other UE send to the 2nd UE etc.

Step 206, the 2nd UE receives and controls the communication information that node sends by the second public MSRP passage;

Step 207, the 2nd UE is processed the sign of data and a UE.

After the 2nd UE receives the communication information, read data in this communication information and the sign of a UE, after the sign of these data and a UE is processed, show the user.Such as, the 2nd UE is converted to user name by the sign of a UE, and is word by Data Integration, user name is showed together with word content to the user.

In sum, the data transmission method that the embodiment of the present invention provides, receive by the first highway of setting up in advance the communication information that the first user equipment UE sends, described the first highway is for transmitting all information between a described UE and described control node, the described communication information carries the sign of data, a described UE and the sign of the 2nd UE, and described the 2nd UE is for receiving the UE of described data; Determine the second highway according to the sign of described the 2nd UE, described the second highway is for transmitting all information between described the 2nd UE and described control node; By described the second highway, the described communication information is transmitted to described the 2nd UE, so that described the 2nd UE is processed the sign of described data and a described UE, having solved IM-AS is respectively two UE and sets up respectively the MSRP passage, form the special-purpose MSRP passage between two UE, communication signaling in the increase data transmission procedure caused, reduce the problem of the performance of terminal, reached the effect of saving communication signaling, promoting the performance of terminal.

Please refer to Fig. 3, it shows the method flow diagram of the data transmission method that another embodiment of the present invention provides.This data transmission method comprises:

Step 301, a UE detects whether with controlling node, set up the first public MSRP passage, and this first public MSRP passage is for transmitting a UE and controlling all information between node; If testing result, for controlling node, having set up the first public MSRP passage, performs step 304; If testing result, for controlling node, not setting up the first public MSRP passage, performs step 302;

Because a UE need to communicate by letter with other UE by controlling node, therefore, a UE, before transmission information, needs to detect and whether with the control node, has set up the first public MSRP passage.Set up the first public MSRP passage if testing result is a UE with controlling node, a UE determines and can and control node communication by this first public MSRP passage, performs step 304; With controlling node, do not set up the first public MSRP passage if testing result is a UE, a UE need to set up this first public MSRP passage with controlling node, performs step 302.

Step 302, a UE sends to controlling node the first message request that carries the sign of controlling node;

Because the first public MSRP passage is a UE and controls the passage between node, therefore, a UE can connect to controlling the node request by the first message request in sip message.Wherein, carry the sign of controlling node in this first message request.

Step 303, control node and receive the first message request that carries the sign of controlling node that a UE sends; Set up the first public MSRP passage according to the sign and the UE that control node;

After the control node receives the first message request, read the sign of the control node in this first message request, according to the sign of this control node, determine that a UE asks to set up the first public MSRP passage, set up this first public MSRP passage.

Step 304, a UE sends the communication information by the first public MSRP passage to controlling node, and this communication information carries the sign of data, a UE and the sign of the 2nd UE, and the 2nd UE is for receiving the UE of data;

In the present embodiment, the RCS normalized definition size of the number in the communication information.Such as, the data word joint number is less than 1.4kbit.If the data that a UE need to transmit are larger, can carry out segmentation to these data, make the data length of each data slot be less than tentation data length, then each data slot is added in the communication information and transmitted.Particularly, the communication information also carries the Data Identification of data and data is carried out to the sheet segment identification of the data slot that segmentation obtains; The one UE can also comprise before sending the communication information by the first public MSRP passage to the control node:

If the data length of data surpasses preset data length, data are carried out to segmentation;

To each data slot after segmentation, data slot is added in a communication information, and the Data Identification in the communication information and sheet segment identification are arranged;

In the present embodiment, Data Identification is used for identification data.After the one UE adds in the communication information by data slot, also need to arrange the Data Identification in the communication information.Preferably, a UE can arrange to the data slot that belongs to same data identical Data Identification, to determine according to this Data Identification which data this data slot belongs to.Wherein, Data Identification can be the Message-ID(message identifier in sip message).

Further, for the position of explicit data fragment in data, with according to the data slot data splitting, a UE also needs to arrange the sheet segment identification in the communication information.Wherein, the sheet segment identification can be the order of generated data fragment, and the fragment that is designated 1, the second data fragment such as, the fragment of first data slot is designated 2 etc.; Perhaps, the sheet segment identification can be the length of data slot, as the Byte-Range(bytes range in sip message), such as, the fragment of first data slot is designated 1-1432, and the fragment of second data fragment is designated 1433-2685 etc.

Step 305, control node and receive by the first public MSRP passage of setting up in advance the communication information that a UE sends;

Because a UE sends the communication information by the first public MSRP passage to controlling node, therefore, corresponding, control node and receive this communication information by this first public MSRP passage.

It should be added that, if a UE is through with and controls communicating by letter between node, at a UE to controlling after node sends the communication information, the one UE can send the disconnection request disconnected to controlling node, and controlling node can disconnect and ask to disconnect the first public MSRP passage according to this.

Usually, the one UE is after finishing communication, can't send this disconnection request to controlling node in time, make a UE and control between node and keep the first public MSRP passage always, caused the waste of the communication resource, therefore, preferably, after controlling the communication information of node by the first public MSRP passage reception first user equipment UE transmission of foundation in advance, can also comprise:

Whether detection again communicates by letter with a UE in the first default duration;

If testing result, for again not communicating with a UE in the first default duration, disconnects the first public MSRP passage.

Control node and can be defined as to first the moment that receives the communication information constantly, and locate backward first based on this first moment and preset duration, obtain second constantly.If control node detect timing reach second constantly before, a UE communicates by letter with controlling between node, this communication is defined as to the first new moment constantly, proceeds detection; If controlling node detects timing and reaches second constantly the time, the one UE and controlling between node does not communicate, and controls node determination the one UE communication that is through with, now, in order to save the communication resource that keeps the first public MSRP passage, control node and can disconnect this first public MSRP passage.Wherein, the first default duration can arrange voluntarily and revise.

Step 306, control node and determine the second public MSRP passage according to the sign of the 2nd UE, and this second public MSRP passage is for transmitting the 2nd UE and controlling all information between node;

Particularly, according to the sign of the 2nd UE, determine the second public MSRP passage, can comprise:

Detect and whether have the second public MSRP passage corresponding with the sign of the 2nd UE;

If testing result, for there being the second public MSRP passage, is selected the second public MSRP passage;
